Cruise NewsIIOE-2 ndash First Expedition December 2015

IIOE India ESSO-Indian National Centre for Ocean Information Services Hyderabad INDIA

The first expedition on board Research Vessel Sagar Nidhi conducted as a part of the IIOE-2 concluded at Mauritius after exploring the western Arabian Sea for 18 days The voyage was flagged of by the Hon Minister of State for Science and Technology and Ministry of Earth Sciences Mr Y S Choudhary at a function held at Mormugao Goa on 4 December 2015

The expedition was led by Prof P N Vinayachandran of the Indian Institute of Science (IISc) Bangalore and Dr Satya Prakash of the ESSO-Indian National Centre for Ocean Information Services (ESSO-INCOIS) Hyderabad Twelve Indian Scientists participated representing IISc INCOIS NIOT (Chennai) NCAOR (Goa) NRSC (Hyderabad) and Goa University In addition to scientists from India there were participants from Mauritius Israel Singapore Australia and the UK

The main goal of this multi-disciplinary scientific expedition was to understand the structure of water masses in the western Indian Ocean along 67degE and assess

the difference in their characteristics with respect to observations made in the past The other objective of the cruise was to understand the physical-chemical-biological characteristics in the equatorial Indian Ocean and their inter-relationships Underwater profiles of currents temperature salinity oxygen light and chlorophyll were measured during the cruise In addition samples have been collected to a depth of 1000 m for various chemical and biological analyses Samples of zooplankton were collected using nets towed from the stern of the ship

It is expected that the data collected during this expedition will elucidate the currents and water masses in the western Indian Ocean in detail and thus further our understanding of the oceanography of the Indian Ocean

The German-Russian expedition KuramBio II with RV Sonne will be performed between 16 August ndash 26 September 2016 to the Kuril-Kamchatka Trench (KKT) There will be 40 scientists on board mainly from Germany and Russia but also with participants from Poland the United Kingdom France Switzerland Mexico Korea and Japan This expedition follows the SoJaBio expedition to the Sea of Japan in 2010 and the KuramBio expedition to the KKT area in 2012 as well as the SokhoBio expedition to the Sea of Ochotsk in 2015 The goals of these expeditions were to study the biodiversity biogeography and trophic characteristics of the benthic organisms in different northwest Pacific deep-sea environments In the KuramBio I samples from depths between 5000-6000 m we could identify more than 1700 benthic species and

at least half of these are new for science The richest samples however have been collected at the slope of the KKT therefore we assume that the v-shaped topography of the KKT might enhance food availability and lead to an even higher biodiversity at larger depths

During the expedition KuramBio II we would therefore like to test the following hypotheses

1) The hadal ecosystem of the KKT is characterized by a high number of species (not lower than in the abyssal plain near the KKT)

2) The number of endemic species will increase with increasing depth in the KKT

3) The hadal depths of the KKT isolate benthic species of the Sea of Okhotsk from species of the abyssal Northwest Pacific

4) The main food source of epibenthic copepods (which we will use as a model taxon for biochemistry) is detritus while planktonic copepods feed mainly on diatoms and microzooplankton

Pourquoi Pas Les AbyssesSophie Arnaud-Haond and Florence Pradillon

IFREMER France Contact abyssfriendsifremerfr

In May 2016 Ifremer the French Institute for Research and Exploitation of the Sea will be launching a new project called ldquoPourquoi Pas les Abyssesrdquo During the past few years New Generation Sequencing allowed fast and great advances in the knowledge of the distribution of microbial life on Earth including prokaryotes and microscopic plankton in the marine realm This project stems from the recognition that much effort is still required to understand the richness and worldwide distribution of eukaryotic communities (including macro and meiofauna) not only in emblematic ecosystems such as cold seeps hydrothermal vents and cold-water corals or seamounts but also in the entire abyssal plain that constitutes the largest ecosystem on Earth The goal of the project is to contribute to a (re) evaluation of the biodiversity present in the abysses and to improve our understanding of its level and history as well as of the possible environmental drivers of its distribution We aim to do so by analyzing the environmental DNA present in the marine sediment and the water layer above A double approach coupled with the morphological determination of fauna will be performed on several pilot sites in the

Atlantic and the Mediterranean To gather the most comprehensive set of samples worldwide following a standardized sampling procedure and to evaluate as comprehensively as possible the level and distribution of deep-sea biodiversity we aim at setting up or strengthening collaborations and partnerships with partners interested from the ldquoDeep-sea biology communityrdquo The project is thus divided in two parts one is based on ongoing and scheduled research cruises where dedicated sampling is planned and the other on a network of partnerships For this last part we chose to standardize the sampling (based on multicore for sediment and Niskin for water samples)

We would like to invite the partners who could be interested in contributing with specific samples from their studied zones to contact us (abyssfriendsifremerfr) so that reciprocating interests can be evaluated together For sites retained as fitting the goals of the project Abyss we will define a specific agreement for the data sharing with each partner engaged

INDEEP WG3 Workshop Biodiversity and connectivity of deep-sea ecosystems in areas targeted by deep-sea mining

Swakopmund Namibia 11 ndash 21 April 2016

The extraction of phosphates from the marine environment has yet to commence anywhere in the world However it is of increasing international interest as a strategic reserve of agricultural fertilizer Representatives from industry see this as a potentially lucrative proposition and are attempting to push forward with instigating their programmes in New Zealand (Chatham Rock Phosphate Ltd) Mexico (Odyssey Marine Exploration) Namibia (Namibian Marine Phosphates) and South Africa (Green Flash Trading amp Diamond Fields International) Currently a high level of scrutiny

of the proposed phosphate mining activities is underway for each of the regions under consideration The results of the Environmental Impact Assessment for both the projects in both New Zealand and Mexico have resulted in denial of licence applications for these projects by the relevant governmental environmental agencies (in February 2015 for Chatham Rock Phosphate Ltd and in April 2016 for Odyssey Marine Exploration) although appeals may well be forthcoming In Namibia a moratorium on phosphate mining has been in place since September 2013 and the governmental evaluation of the recent EIA is about to commence

INDEEP scientists have been keeping abreast of the marine phosphate-mining situation worldwide and Namibia in particular largely owing to links with our INDEEP colleague Mrs Bronwen Currie a biologist in the Namibian Ministry of Fisheries and Marine Resources We were fortunate enough to meet Bronwen during the 13th Deep-Sea Biology Symposium in NZ in 2012 (her attendance was enabled by the INDEEP-International Seabed Authority travel bursary award) It was during this meeting that our first discussions regarding a potential INDEEP capacity development effort in Namibia took place Bronwen explained that despite the wealth of fisheries scientists in Namibia there are almost no deep-sea benthic ecologists This poses a problem in light of the proposed mining We subsequently collaborated with Mr Rudi Cloete of the Ministry of Fisheries and Marine Resources to hold a workshop in order to address this limited capacity in Namibia in terms of benthic and pelagic ecosystem effects of mining The workshop would consider not only the fundamental principles of benthic ecology but also would address the main concerns of a variety of deep-sea anthropogenic activities We secured funds from the INDEEP grant (funded by Fondation Total) and this was generously matched by funds from the International Seabed Authority These funds enabled us to invite 28 participants from Namibia Kenya Madagascar Mauritania and Angola to attend the workshop in Swakopmund at the National Marine Information and Research Centre of the Ministry of Fisheries and Marine Resources headquarters Their experience spanned sectors and disciplines although most were related to fisheries in some way and included an Executive Director of the Centre of Studies and Development of Fisheries Senior Fisheries Biologists Head of Data Management PhD Students Fisheries Research Technicians and Research Scientists

A diverse range of subjects was taught using a variety of methods Participants were introduced to benthic environments and the associated fauna the history of deep-sea exploration animal-sediment interactions human impacts sampling and sampling design metrics used in characterisation of the benthos ecosystem function and Above A selection of images from the well-attended workshop

services life-histories larval dispersal and connectivity consideration of mining impacts management strategies and governance The teaching comprised a combination of lectures hands-on investigations of benthic fauna (from meio to megafauna) including boat work sample processing laboratory observations data analysis exercises discussion groups and feedback presentations by participants The course preparation was a dynamic process with adjustments made by the presenters each evening based on participant requirements in preparation for the following day All participants were given access to the course presentations associated key literature and webinar recordings They were also given course participation certificates Post-course evaluations were extremely positive with the majority of participants eager to use their new knowledge in their current roles to varying degrees and to pass on this knowledge to their colleagues In addition it is hoped that benthic monitoring becomes incorporated into standard practices in Namibian waters alongside fisheries assessments Others are now considering a change of career path in order to incorporate or even focus on benthic research The enthusiasm of the participants was evident throughout and each one is now far more aware of how the benthic and pelagic ecosystems are interlinked and hence should be considered in any marine industrial impact assessments The INDEEP presenters also gave feedback and each thoroughly enjoyed their experience of teaching in Namibia The group worked well together and it is envisaged that this new network will be of use to many of the participants and presenters alike It is hoped that some of the Namibia workshop participants may teach in future INDEEP capacity development efforts Overall this workshop was a great success

Connecting Connectivity in the Clarion-Clipperton ZoneReport written by Dr Adrian Glover Research Leader Natural History Museum httpwwwnhmacukdeep-sea

Researchers from across the European Union meet at the Natural History Museum in London to discuss and integrate new molecular biodiversity data from the worldrsquos largest mining exploration zone

Over the course of three days in May 2016 thirty-two scientists met at the Natural History Museum in London to work on one of the most difficult problems in deep-sea environmental management the regional biodiversity connectivity and biogeography of the Clarion-Clipperton Zone (CCZ)

Jointly organised under the auspices of the ldquoManaging Impacts of Deep-sea Resource Exploitationrdquo (MIDAS) and ldquoEcological Aspects of Deep-sea Miningrdquo (under the Joint Programming Initiative - Healthy and Productive Seas and Oceans) European Union (EU) projects with input from the International Seabed Authority (ISA) and the ABYSSLINE consortium the meeting was developed to bring together principal investigators post-doctoral researchers and PhD students from recent EU-led projects in the CCZ The focus was on presenting new molecular-based data that have been collected in a series of recent expeditions linked to the MIDAS and JPI-Oceans projects

It has been widely recognised that a major problem in the development of environmental guidelines for both mineral exploration and exploitation in the CCZ is the lack of regional-scale baseline data on species-level biodiversity biogeography and connectivity (eg ISA 2014 amp 2015 Seascape Consultants 2014) New molecular-based assessments of CCZ biodiversity (eg Janssen et al 2015 Glover et al 2016a) are starting to offer new data from within contractor exploration zones and provide an opportunity to integrate data into a synthetic regional-level approach

The workshop was organised around three topics (1) new molecular data on species taxonomy and distributions within and between CCZ exploration zones (2) new intra-specific population genetic data on lsquotarget taxarsquo and (3) broader-

scale (ocean-basin and global) biogeographic data based on both traditional morphological information and molecular data The scope of the discussions were focussed taxonomically on metazoan animals and foraminiferal protists in particular on meiofaunal (eg copepods and nematodes) and macrofaunal (eg polychaetes isopods and molluscs) size classes for which there are the most data while some new data are starting to appear on the larger megafaunal animals which are difficult to sample in the CCZ (eg holothurians and corals)

On 10th May 2016 the workshop convened at lunchtime in the Board Room of the Natural History Museum with overviews from the main EU-sponsored sampling projects in the CCZ This was followed by a presentation from the ISA on ongoing policy needs and implications and a presentation from an industry perspective from UK Seabed Resources Ltd These latter talks were designed to focus the scientific discussions planned for the second day on stakeholder needs and perspectives The day ended with an informal social in the Hereford Arms pub where workshop participants were able to continue discussions over local London ales

The second day got off to a surprising start with the workshop participants having to make their way through a museum filled with a large film production team from Universal Studios filming lsquoThe Mummyrsquo starring US actor Tom Cruise Several of the workshop group met Mr Cruise acting in the central hall beneath the statue of Charles Darwin and inadvertently found themselves as extras in the production After this slight delay the somewhat star-struck group then got down to work with the main data sessions of the workshop An impressive array of new data were presented from recent cruises and subsequent analyses principally from the eastern CCZ focussed around the exploration zones of the UKSRL (UK) BGR (Germany) IFREMER (France) GSR (Belgium) and IOM (Bulgaria Cuba Czech Republic Poland Russia and Slovakia) New DNA sequence data were presented from all these regions from a wide range of taxa and across sampling sites at spatial scales of 60 to 1300km

A common theme from the data sessions emerged that the majority of teams were now using DNA sequences from typical invertebrate genetic markers (eg COI 18S 16S 28S) to delimit lsquospeciesrsquo based on either lsquobarcoding-gaprsquo analysis andor phylogenetic reconstruction using additional published sequences (Glover et al 2016b) These lsquospeciesrsquo referred to by several teams as ldquoMolecular Operational Taxonomic Unitsrdquo (MOTUs) were then examined for their distributional range and in some instances particularly abundant species (target taxa) selected for more detailed population genetic study Examination of morphology within DNA-delimited species was then also providing valuable biogeographic data to enable in some instances comparisons within or even between ocean basins The second day finished with the workshop dinner held in the famous Polish Club restaurant next to Imperial College in South Kensington

The final day of the workshop was designed to utilize the combined knowledge at the table to create a matrix of ongoing and planned work activities (eg manuscripts in preparation intended grant proposals and future cruises) An impressive list of planned publications was generated that included 44 planned scientific papers for the next 3 years from the workshop The creation of this list also highlighted many options for collaboration including both specimen and data sharing amongst academic and contractor-led projects In addition discussion was focused onto the generation of workshop outputs in particular a published and open workshop report and the potential for a synthetic paper highlighting selected new data It was agreed to produce a workshop report containing a useful overview of

The ALOHA Cabled Observatory (ACO) is a general purpose ldquonoderdquo for science use at Station ALOHA 100 km north of Olsquoahu (left) Included are a suite of basic sensors making core measurements some local and some sensing the water column At 4728 m deep it is the deepest scientific outpost on the planet with power and Internet including cameras and lights Investigators are encouraged to propose projects using these capabilities See httpaco-ssdssoesthawaiiedu

Deep-sea life has been observed using a camera tripod with a pantiltzoom camera at ~2 m above the seafloor with off-axis lighting Animals include crabs (Munidopsis sp) crawling over the observatory framework and the first observation of a lizard fish (Bathysaurus mollis) attacking an aristeid shrimp On average about one organism per 40 minutes was observed Analysis of 40 days of video revealed that aristeid shrimp holothurians and polychaetes often ones drifting past in the water column were the most commonly observed species

Other organisms have been observed from remotely operated vehicles (ROVs) A ldquosail-equippedrdquo sea cucumber was seen while servicing the observatory (Psychropodes sp ROV Lulsquoukai 20150920) What is thought to be a new species of octopod was observed during one of the installation cruises (ROV Jason 20110528 on Kalsquoena Ridge at 3116 m red dot on map) There have been two other recent sightings of this animal and a publication is in preparation

Deep-sea scientific research was in the spotlight at the first Preparatory Committee meeting for the development of an international legally-binding instrument under the 1982 United Nations Convention on the Law of the Sea (UNCLOS) on the conservation and sustainable use of marine biological diversity in areas beyond national jurisdiction (ABNJ) In this vast space covering more than 65 of the ocean a new instrument will address gaps in the international legal framework for marine life through area-based management tools environmental impact assessment marine genetic resources (MGR) capacity development and technology transfer A DOSI Deep-Sea Genetic Resources (DSGR) Working Group submission highlighted the critical role of deep-sea scientific research in addressing MGR governance issues including access and benefit sharing

The submission was made by IUCN on behalf of the DOSI DSGR Working Group and used in various interventions at the first Preparatory Committee meeting (28 March ndash 8 April 2016) in New York to highlight the role of marine science in developing options The submission -which drew from results of a survey of some INDEEP and DOSI members - highlighted that scientific knowledge data and samples are significant benefits from MGR in ABNJ It called for support for deep-sea science in ABNJ enhanced international cooperation and avoiding obstacles to research It highlighted that existing best-practice approaches in science provide a strong basis to facilitate open-access to data and samples of MGR from ABNJ

Many science issues were raised in the Preparatory Committee discussions with delegations broadly agreeing on the need for a pragmatic approach towards equitable benefit sharing in order to bridge divergent views on governing principles for MGR in ABNJ Some highlighted the need for a lsquolightrsquo regime that promoted research development and the sharing of data and knowledge However additional support mechanisms would be needed to facilitate access and benefit sharing and strengthen capacity in developing States Dr Judith Gobin of the DSGR Working Group attended the meeting as part of the IUCN delegation with the financial support of the PharmaSea project together with Kristina Gjerde A Chairrsquos overview of this first PrepComm session is now available online httpwwwunorgdeptslosbiodiversityprepcom_filesPrepCom_1_Chairrsquos_Overviewpdf

We thank the DOSI DGSR Working Group members (especially Maria Baker Angelika Brandt Judith Gobin Tammy Horton Marcel Jaspars Roser Puig and Elizabeth de Santo) for their contributions to the development of the submission and we are grateful to all the DOSI and INDEEP members who

contributed through the survey

The second Preparatory Committee meeting will be held 26 August - 9 September 2016 The DSGR Working Group will continue to provide input to the Preparatory Committee process and will further examine issues raised in the survey including how a new instrument can facilitate not hinder marine scientific research The Working Group welcomes further input from INDEEP and DOSI to contribute to the next phase of DSGR Working Group activities and ensure that the voice of deep-sea science is clearly a part of these historic negotiations

Coming Soon as part of the Global Ocean Observing System (GOOS) a project focused on the creation of a Deep Ocean Observing Strategy or DOOS

Deep ocean observation is a science and technology challenge addressing the grand societal issues of climate change adaptation ecosystem conservation and sustainable management Please visit the project website wwwdeepoceanobservingorg

DOOS Objective

Develop a common statement of requirements and an initial strategy for sustained global deep ocean observations considering all Essential Ocean Variables regions and technologies so as to extract high priority feasibility and GOOS fit-for- purpose actions for the next 5-10 years

DOOS Approach

Catalyze coordination among existing efforts and use the Framework for Ocean Observing as our strategic guide This approach will result in a multi-disciplinary strategy capitalizing on best practices realized across ocean observing systems

Engagement

To be successful DOOS will require partnerships participation and consultation from the deep-sea observing community Among these groups are Deep Argo Go-SHIP Satellites Deep Observatories Moorings Time Series Stations Gliders IOC- GOOS Projects and Regional Alliances DOSI and links to other national and international programs

New portal for deep-sea discoveriesNeil Golding

WGDEC Chair ICESNAFO

Contact Neilgolding jnccgovuk

Portal recently launched by International Council for the Exploration of the Sea (ICES) visualizes all known vulnerable marine ecosystem (VME) data in the North Atlantic

Vulnerable marine ecosystems (VMEs) are deep-sea ecosystems that can be adversely impacted by bottom-contact fishing gear VMEs include cold-water coral reefs coral gardens and deep-sea sponge aggregations It is quite difficult to positively identify VMEs in deep water without using specialist underwater camera equipment However ldquoVME indicatorsrdquo are a start for investigation A VME indicator is a species from a broad group of benthos that is found in trawl bycatch for example sponges gorgonians or stony corals Their presence indicates that there may be an actual VME habitat on the seabed ndash for example gorgonians may be a component of coral garden VMEs

The ICESNAFO Working Group on Deep-water Ecology (WGDEC) evaluates data on the presence of VMEs in the deep sea in the North Atlantic Over the past few years the group and the ICES Data Centre have been developing a data portal that publicizes all data on the distribution and abundance of VMEs (and species considered to be indicators of VMEs) across the North Atlantic

Neil Golding Chair of WGDEC explains ldquoPeople can now map and explore the data from the VME database and the key thing about the portal is that it differentiates between the VME indicators (often recovered as by-catch) and the VME habitats (observed in situ on the seabed)rdquo

Weighting system

Some VME indicators can be misleading but the group has developed a weighting system to tackle the issue

This system looks at the number of VME indicator records for a particular area (presented on the map as a 005degx 005deg c-square) It evaluates how many records there are of particular VME indicators where the indicators have come from and the survey method used (trawl longline bycatch or camera) This evaluation leads to a score as to the likelihood of a VME being present

Golding feels this new weighting system will be extremely valuable ldquoIn the past when we (WGDEC) have been requested to provide recommendations on bottom-fishing closures to protect VMEs it has been difficult to know how much confidence to have in the VME indicators If it was a video transect then you have high confidence but if it was a bycatch of some coral then there might not be a VME down there Thatrsquos why this system is really importantrdquo

Transparency

Displaying all VME data being used by the group ensures that all data underpinning WGDEC recommendations (such as bottom fishing closures) is now visible ldquoThe key thing is that users can now see this The portal represents the first time we have had these data out in the open People can now click on the different VMEs and the different indicators

12


They can look at the recommendations made by WGDEC for bottom fishing closures formal ICES advice which is provided to ICES clients and the actual closures enacted by the regional fisheries management organisations All this can be viewed on the one map as different layers It makes the process so much more transparent Advice clients and stakeholders can see what wersquore doing I think itrsquos really impressiverdquo

Sponge-dominated communities of the deep-sea have been increasingly recognized as important ecosystems providing numerous goods and services to our planet and ultimately to us humans Yet sponge grounds have been thus far the most overlooked ecosystem of the deep-sea For instance major knowledge gaps exist about basic aspects of their biology and ecology their contribution to global biogeochemical cycles their role in supporting economy eg through fisheries and the impact that human activities may have upon them

This is where a small yet international team of researchers took off Could they fill in such gaps deliver innovation and ndash at the same time ndash inform management towards sustainability The core of SponGES was born Yet it took two more years and a set of calls in the framework of the European Commissionrsquos Horizon 2020 Blue Growth Programme to launch such a project

SponGES ndash Deep-sea Sponge Grounds Ecosystems of the North Atlantic an integrated approach towards their preservation and

sustainable exploitation started in March 2016 and will run for 4 years pooling together the expertise and facilities of 19 European Canadian and American partner institutions SponGES will

bull Improve the capacity to model understand and predict threats and impacts and future anthropogenic and climate-driven changes to sponge grounds

bull Advance the science-policy interface and develop tools for improved resource management and good governance of these ecosystems from regional to international levels across the North Atlantic

SponGES will use its transdisciplinary consortium and its state-of-the-art operational and technological capacity to study all of the main types of deep-sea sponge ecosystems known to occur in the North Atlantic all the way from the Arctic southwards to the Azores archipelago including sites from both the western and the eastern Atlantic In-situ observation and experimentation will be combined with novel approaches in the fields of experimental ecology and physiology ldquoomicsrdquo biotechnology and modelling

With the participation of (and co-coordination by) American and Canadian partners this project will genuinely work at a trans-Atlantic level bringing the Galway Statement vision on Atlantic Ocean research cooperation forward

The year 2015 set the stage to one of the most exciting research projects to date in the Galapagos since Charles Darwin visited the islands in 1835 Despite the coastal waters and emerged volcanoes of this remote Eastern Tropical Pacific island chain having received great scientific interest since Darwinrsquos revolutionary theory the depths of the Galapagos have remained vastly unexplored The project ldquoSeamounts of the Galapagos Marine Reserve (GMR)rdquo has recently gained momentum and international attention due to the unprecedented number of deep-sea research expeditions completed last year The Charles Darwin Foundation (CDF) with the support of the Galapagos National Park Directorate (GNPD) is working in close collaboration with the Woods Hole Oceanographic Institution the Ocean Exploration Trust and the National Geographic Pristine Seas Initiative as the main partners in this project

Over the past six months three deep-sea exploration vessels (MV Alucia EV Nautilus MV Argo) with four different submersibles allowed the project partners to conduct 70 submersible dives to depths of up to 3600 m across the different bio-regions of this iconic archipelago A total of 25 seamounts were explored and sampled together with a

range of other deep-sea habitats including hydrothermal vents abyssal slopes and deep lava flows When it comes to biology numbers become overwhelming and highlight the great amount of work ahead 45000 photos 200 hours of submersible footage and over 500 samples of unique deep-sea specimens have been collected This unprecedented dataset constitutes a comprehensive deep-sea biodiversity baseline study for the region Preliminary reports from taxonomic experts have revealed that many specimens collected are likely to be new species to science

Individual researchers or institutions interested in deep-sea research are more than welcome to contact CDF to explore ways of collaborating Graduate student and volunteer positions are opened year round at the Charles Darwin Research Station marine lab for collaborators willing to bring their support to the project and enjoy Galapagos unique lifestyle

to different populations The use of molecular-genetic methods with the application of various genetic markers (Cyt b control region microsatellites etc) and modern software will give us an opportunity to investigate intra-species organization of Antimora spp in their main habitation areas (North Atlantic North Pacific Antarctic) It will also allow us to study microevolutionary processes that occurred in their populations in recent historical times including the time of descent from a common ancestor pathways of subsequent dispersion and demographic history

Report on the cost-benefit analysis of deep-sea mining in the Pacific RegionOnorina Saukelo SPC-EU Deep Sea Minerals Project Fiji

A report on ldquoAn Assessment of the Costs and Benefits of Mining Deep-Sea Minerals in the Pacific Island Regionrdquo is now publicly available online at httpgsdspcintdsmimagespdf_filesPIR_CBA_Report

Commissioned by the Pacific Community (SPC) through the European Union-supported Deep Sea Minerals Project the report aims to assist Pacific Island countries in making sound deep-sea mining related decisions The report provides information about the potential magnitude of the impacts of deep-sea mining and offers decision-makers insights into the potential constraints and challenges to achieving positive net benefits if deep-sea minerals mining were to occur under current circumstances

Cardno an infrastructure and environmental consultant firm was contracted to conduct the cost-benefit analysis (CBA) between 23 February and 16 October 2015 For the purpose of the CBA Cardno assembled a strong team of resource

economists and environmental scientists with decades of experience in natural resource economics impact and risk assessments sustainable economic development and ecological restoration in deep-sea and reasonable involvement in DSM related activities

Based on the resource potential of three of the project countries the CBA considers the monetary value of all aspects of mining seafloor massive sulphides in Papua New Guinea manganese nodules in Cook Islands and cobalt-rich crusts in the Republic of the Marshall Islands

The report interestingly found that seafloor massive sulphide mining in Papua New Guinea has benefits that significantly outweigh the costs Also it revealed the mining scenario in the Cook Islands (where four metals are recovered and the miner owns the operation and the processing facility overseas) has the highest net benefits However the report states that crust-mining in the Marshall Islands under the two scenarios considered is currently not economically viable due to present metal prices expected ore recovery and costs of technology

The report concluded that as long as proper steps are taken to manage the wealth in the long-term and to transfer the environmental risk from the people of the host country to the mining company there is a higher possibility of the social benefits outweighing the social costs

Despite the studies limited focus on three countries the report provides important findings and considerations that are applicable to other Pacific nations with similar deep-sea mineral resources

Major Push to Conserve Life in the Oceans The German Federal Ministry for the Environment Nature Conservation Building and Nuclear Safety (BMUB) has given the green light to an intensive five-year effort to support conservation of life in the deep seas and open oceans

The Global Ocean Biodiversity Initiative (GOBI wwwgobiorg) a successful international partnership of more than 30 marine scientific institutions that has been advancing the scientific basis for conserving marine biodiversity since 2008 has been awarded a grant of euro52m from the German International Climate Initiative1 GOBI is coordinated by Seascape Consultants a UK-based company specialising in transformational policy advice for ocean planners and managers and Prof Dr Henning von Nordheim of the German Federal Agency for Nature Conservation (BfN) will continue to provide scientific guidance and oversight

Professor David Johnson GOBI Coordinator explains ldquoThis is a really exciting opportunity to support Parties to the Convention on Biological Diversity (CBD) who have made commitments to conserve marine biodiversity To help policy-makers make the right decisions we need to better understand essential ocean processes functions and interactions Detailed scientific and technical advice can inform and influence where and what to protect as a top priorityrdquo

GOBI will help CBD2 determine the strengths challenges and limitations of data availability This includes current and emerging techniques methodologies and expert knowledge In data-deficient regions predictive modelling of the occurrence abundance movement and range of species or ecosystem features will play an important role GOBI will therefore contribute to the CBDrsquos Strategic Plan for Biodiversity which established a series of Aichi Biodiversity Targets to be reached by 2020 by working up detailed biological information ocean biogeographies and by integrating data on migratory species and hydrothermal vent ecosystems

Working with more than 100 countries over the past five years the CBD has masterminded a process of regional workshops to describe Ecologically or Biologically Significant Marine Areas (EBSAs) With most of the worldrsquos oceans now assessed by this process the onus is now to balance conservation and human activities incorporate traditional knowledge and contribute to sustainable livelihoods GOBI will be working with a range of these countries including Small Island Developing States of the south-west Pacific developing countries of the Western Indian Ocean and Central American States including Guatemala El Salvador Costa Rica Panama Nicaragua and Honduras Results will feed into the international debate on protecting the ocean including negotiations for a legally binding instrument to protect High Seas biodiversity and Sustainable Development Goal 14 They should also inform global bodies such as the International Seabed Authority and regional organisations such as the Secretariat of the Pacific Regional Environment Programme

The scientific partners in the project reflect its global nature They comprise

bull The Tethys Research Institute based at the City Aquarium of Milan specialising in marine mammal conservation with an impressive track record of success in the Mediterranean

The deep-seas and open oceans are home to a major part of the worldrsquos biodiversity They support an enormous wealth of productive ecosystems specialised habitats and individual species which collectively provide humankind with services such as the production of oxygen food and the regulation of the Earthrsquos climate However these ecosystems and the services they provide are under increasing pressure from global-scale issues such as climate change and from human activities such as resource exploitation over-fishing shipping and coastal development

Area-based management approaches and tools can help address a multitude of threats These tools include marine protected areas and networks environmental impact assessments improved regulation of sectoral activities and broader ecosystem-based marine spatial planning GOBI will continue to support such work while improving the scientific basis of CBD Decisions UN resolutions and other measures through the application of analyses network design training and capacity building

Background

The South Orkney Islands is a small archipelago located in the Southern Ocean 375 miles north-east of the tip of the Antarctic Peninsula The seafloor around the South Orkney Islands has been shown to be an area with exceptionally high biodiversity The Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) closed all finfish fisheries around the South Orkney Islands in 1989 and in 2009 they established the South Orkney Islands Southern Shelf Marine Protected Area (SOISS MPA) the first MPA located entirely within the High Seas anywhere on the planet

SO-AntEco (JR15005) was a British Antarctic Survey (BAS) led expedition undertaken in conjunction with an international team of scientists from the Scientific Committee for Antarctic Research (SCAR) AntEco research programme The team included 22 participants from 9 different countries and 16 institutes The expedition took place on board the RRS James Clark Ross in February-March 2016

NewsOutreach at new depths ndash Live Dive Event at hydrothermal vents between Fiji

and Tonga lsquoedutainsrsquo the next generation of ocean ambassadorsA group of 70 students and teachers from high schools in Victoria BC and online viewers were lsquoedutainedrsquo through a live ship-to-shore connection with a hydrothermal vent expedition in the territorial waters of the Kingdom of Tonga on April 29th 2016

The event demonstrated the value of collaborating across multiple institutions when it comes to engaging the next generation of ocean ambassadors with deep-sea exploration The Live Dive was a unique combination of live broadcasting online participation and classroom engagement

High school students participating in the 4th Annual Ocean Science Symposium by Ocean Networks Canada (ONC) were given the opportunity to interact with deep-sea specialists on the Schmidt Ocean Institutersquos Research Vessel Falkor via live-link in an auditorium and via Twitter High-definition video footage from the ROPOS Remotely Operated Vehicle on-board RV Falkor was streamed through live-link whilst experts discussed hydrothermal vent science and explained the biological interactions playing out on the screen Questions from both the physical and online audiences were fielded and answered in real time

Dedicated classroom materials were prepared for participating schools and made available online prior to the event enabling teachers to integrate hydrothermal vents into their lessons The students participating in the auditorium were also given the chance to see actual deep-sea specimens and ask scientists questions informally after the live-link

The student reactions to the Live Dive demonstrated the power of live interaction and lsquoedutainmentrsquo

laquoThe Falkor live dive was really cool I found it especially interesting because it followed the hydrothermal vent presentation and the ability to ask questions directly to the researchersrdquo

ndash High school student

ldquohellip the Fiji Live Deep Sea Diving was truly an amazing experience allowing people online to actively participate in the event is a really practical and efficient way to raise awareness and share the fun This is the kind of project that could really in my opinion bring science lsquofield tripsrsquo to a new level I canrsquot wait for the next onerdquo

Conserving the other 50 of the world status and opportunities in area-based management beyond national jurisdiction

A pre-IMCC focus group open to public registration 28-29 July 2016

St Johnrsquos Newfoundland

This past June the UN General Assembly adopted a resolution to establish a Preparatory Committee (PrepCom) to begin negotiations on a new legally-binding instrument for the conservation and sustainable use of marine biological diversity beyond national jurisdictions This consensus resolution marks both the culmination of a herculean 10-year effort to bring this topic to the floor of the UNGA and at the same time the first step in a larger process The negotiations that will ensue over the next two years will set the stage for the conservation of biodiversity for the other 50 of the planet and represent an enormous opportunity to inform conservation policy and effect change In this focus group we will examine the status and opportunities for conservation of ABNJ by reviewing new scientific findings and current sectoral efforts to conserve biodiversity We will synthesize this information and consider how it can inform a new legally-binding instrument and the role of civil society in the process

IMCC 4 precedes the second meeting of the BBNJ PrepCom by just a few weeks The main objective of this focus group will be to develop a high level policy brief describing the status and opportunities for the conservation and sustainable use of ABNJ for that PrepCom meeting The policy brief will be distributed at a side event at the PrepCom along with a summary presentation of our findings The focus group will target three of the four elements of the ldquopackagerdquo being negotiated at the PrepCom including area-based management tools environmental impact assessments and capacity building and technology transfer We will also review scientific evidence for anthropogenic impacts on the open oceans and deep seas to set the stage for the need for the new instrument While input from the scientific community is critical to this process we also seek to provide information to scientists and civil society more broadly by providing in depth explanations of the history and relevance of the BBNJ PrepCom negotiations

We could not be more excited about the line-up of speakers (see draft agenda below) and the potential the workshop has to inform the negotiations of a new international legally-binding instrument While there are numerous speakers the main purpose of this focus group is to get feedback from the community on the most important elements to include in the policy brief As such have allowed significant time for discussion after each session of speakers We sincerely hope you will join us for the focus group and contribute your voice to this effort

Please note you need to register for the focus group through the conference website

James_chesso

I am a third year deep-sea ecology PhD student in the UK My general research interests are in the environmental controls that act upon deep-sea benthic assemblages I have previously worked on the ECOMAR project (Bell et al 2013 in press) and currently I am studying assemblage and trophic structure in several chemosynthetic ecosystems from the Southern Ocean (Bell et al 2016 submitted in prep) During my PhD research I am working to establish how environmental variation at deep-sea sediment-hosted chemosynthetic ecosystems structures differences in assemblage and trophic ecology This project involves a suite of analyses including community ecology stable

isotope analysis amp mixing models geochemistry and food web modeling

I completed my Master of Marine Biology degree (MSci) at Southampton University in 2012 (Bell et al 2013 DSR II) In 2012 and 2013 I worked on benthic megafaunal structure on steep areas of the Mid-Atlantic Ridge (Bell et al in press Marine Ecology) after which I began my PhD studies primarily based at Leeds University I expect to complete my thesis in February 2017 which will be comprised of four lead author papers focusing mainly upon the ecology of a sedimented hydrothermal vent system in the Bransfield Strait Antarctica (see Bell et al 2016 Frontiers in Marine Science) but also investigating the ecological effects of reducing sediments enriched in methane (Bell et al submitted) I am actively involved in partnerships with the University of Newcastle and the Royal Netherlands Institute of Sea Research contributing to my PhD thesis papers as well as some additional research (eg modeling isotopic characteristics in food webs) I am also active in science engagement and won a UK science engagement contest in 2014 and I have even done academic stand up a couple of times with mixed success

I am looking for projects along a deep-sea ecology theme to start in the first half of 2017 If you know of anything please let me know

Cutting the Umbilical New Technological Perspectives in

Benthic Deep-Sea Research

Many countries are very active in marine research and operate their own research fleets In this decade a number of research vessels have been renewed and equipped with the most modern navigation systems and tools However much of the research gear used for biological sampling especially in the deep-sea is outdated and dependent on wired operations The deployment of gear can be very time consuming and thus expensive The present paper reviews wire-dependent as well as autonomous research gear for biological sampling at the deep seafloor We describe the requirements that new gear could fulfil including the improvement of spatial and temporal sampling resolution increased autonomy more efficient sample conservation methodologies for morphological and molecular studies and the potential for extensive in situ real-time studies We present applicable technologies from robotics research which could be used to develop novel autonomous marine research gear which may be deployed independently andor simultaneously with traditional wired equipment A variety of technological advancements make such ventures feasible and timely In proportion to the running costs of modern research vessels the development of such autonomous devices might be already paid off after a discrete number of pioneer expeditions

Improving the estimation of deep-sea megabenthos biomass dimension to wet weight conversions for abyssal invertebrates

Durden JM Bett BJ Horton T et al (2016)

Marine Ecology Progress Series doi 103354meps11775

Deep-sea megafaunal biomass has typically been assessed by sampling with benthic sledges and trawls but non-destructive methods particularly photography are becoming increasingly common Estimation of individual wet weight in seabed photographs has been achieved using equations obtained from measured trawl-caught specimens for a limited number of taxa However a lack of appropriate conversion factors has limited estimation across taxa encompassing whole communities Here we compile relationships between measured body dimensions and preserved wet weights for a comprehensive catalogue of abyssal epibenthic megafauna using ~47000 specimens from the Porcupine Abyssal Plain (NE Atlantic) housed in the Discovery Collections The practical application of the method is demonstrated using an extremely large dataset of specimen measurements from seabed photographs taken in the same location We also collate corresponding field data on fresh wet weight to estimate the impact of fixation in formalin and preservation in industrial denatured alcohol on the apparent biomass Taxa with substantial proportions of soft tissues lose 35 to 60 of their wet weight during preservation while those with greater proportions of hard tissues lose 10 to 20 Our total estimated fresh wet weight biomass of holothurians and cnidarians in the photographic survey was ~20 times the previous estimates of total invertebrate biomass based on trawl catches This dramatic uplift in megabenthic biomass has significant implications for studies of standing stocks community metabolism and numerical modelling of benthic carbon flows

Bathymetric and regional changes in benthic macrofaunal assemblages on the deep Eastern Brazilian margin SW Atlantic

Bernardino AF Berenguer V amp Ribeiro-Ferreira VP (May 2016)

Deep Sea Research I 111 110-120 doi 101016jdsr201602016

Deep-sea continental slopes have valuable mineral and biological resources in close proximity to diverse and fragile marine benthic ecosystems The eastern Brazilian Continental Margin is an important economic region for both fishing and oil industries but is poorly understood with respect to the structure of the soft-sediment benthic fauna their regional distribution and their bathymetric patterns In this paper we quantified spatial and temporal patterns of benthic macrofaunal assemblages on the slope (400 to 3000 m) across 42 stations as part of the Espirito Santo Basin Assessment Project (AMBES coordinated by Cenpes-Petrobras) We reported bathymetrical and regional (within-depth) changes in assemblage structure and describe previously unknown water mass influences on the deep-sea Espirito Santo Basin In general we reported that macrofaunal assemblages on the slope of Espirito Santo Basin are similar to other areas of the SE Brazilian margin but regional changes in response to productivity and depth need to be considered for management strategies in the face of increasing economic activities off-shore We intend to use the knowledge produced in this study to help the spatial management planning on the deep-sea Brazilian margin

Report of the Joint ICESNAFO Working Group on Deep-water Ecology (WGDEC)

15ndash19 February 2016 Copenhagen Denmark

On 15th February 2016 the joint ICESNAFO Working Group on Deep-water Ecology (WGDEC) chaired by Neil Golding (UK) and attended by eleven members met at ICES HQ Copenhagen Denmark

WGDEC was requested to provide all new information on the distribution of vulnerable marine ecosystems (VMEs) in the North Atlantic A total of 487 new records from within the NEAFC and NAFO Regulatory Areas (RA) and areas within the EEZs of member states were submitted and appended to the ICES VME database The new data were from a range of sources including fisheries and scientific visual seabed surveys No recommendations were made for the modification of existing or creation of new bottom fishing closures

WGDEC sought to refine the VME indicator weighting system developed through 2014 and 2015 In addition WGDEC consolidated a number of approaches for the delineation of bottom fishing closures providing some lsquoguiding principlesrsquo in order to help standardise the delineation of closures when considering a range of different data types

The new ICES VME Data Portal was launched For the first time users can view and download data on VME indicators and habitats used by WGDEC

Finally WGDEC contributed to a request from the European Commissionrsquos Environment Directorate-General (DGENV) to ICES to provide guidance on the interpretation of bottom fishing pressure maps in relation to impacts on benthic habitats and the related indicators across an EU regional scale Specifically WGDEC collated habitat sensitivity information for each deep-sea benthic habitat to fishing pressure for presentation at WKFBI (ICES Workshop on Fisheries Benthic Impacts)

Surfing the vegetal pole in a small population extracellular vertical transmission of an lsquointracellularrsquo deep-sea clam symbiont

Ikuta T Igawa K Tame A et al (2016)

Royal Society Open Science doi 101098rsos160130

Contact teikutajamstecgojp

Transmission of symbionts is a key event in ecological success of the symbiotic systems and in the genome reductive evolution of symbionts However despite their biological significance mechanisms of symbiont transmission are not well understood Deep-sea vesicomyid clams including the genus Calyptogena harbour sulphur-oxidizing intracellular symbiotic bacteria which have a reduced genome in their gill epithelial cells and nutritionally depend on their symbionts It has been believed that the symbionts of vesicomyid clams are vertically transmitted with occasional horizontal mode

37


and that a small population size of the symbiont transmitted via eggs affected their genome reduction However the question how the symbiont associates with the spawned eggs has remained unanswered and the population size of the symbionts transmitted via eggs has not been determined In this paper we show that the symbionts are located on the outer surface of the egg plasma membrane at the vegetal pole and that each egg carries approximately 400 symbiont cells each of which contains close to 10 genomic copies Our results explain longstanding enigmatic problems in the deep-sea clam symbiosis ie the leakiness of the vertical symbiont transmission and narrowness

of the bottleneck of the symbiont population size during the transmission process Our findings shed light on the mechanisms of symbiont transmission and the population dynamics underlying genetic drift and genome evolution in microorganisms and also bring a new dimension to the embryological study of chemosymbiotic animals

Parasitic nematodes have evolved to exploit a wide variety of hosts living in a range of marine environments Benthimermithid nematodes occur deeper than any other nematode parasites (down to 5880 m depth) but are mostly known from free-living adult stages living in the sediments and parasitic juveniles are seldom encountered In the present study the benthimermithid Trophomera cf marionensis was discovered in the body cavity of the lysianassoid amphipod Hirondellea dubia sampled between 7018 and 10005 m depths in the Kermadec Trench The nematode specimens which could be readily observed through the transparent exoskeleton of freshly caught amphipods were up to twice the length of T marionensis specimens described from the Atlantic and East Pacific Oceans but were otherwise morphologically identical Because of its wide geographical and water depth distribution (almost 10000 m) T

marionensis likely consists of several cryptic species The prevalence of Trophomera parasites among the host population was estimated to be less than 1 such a low proportion of parasitised hosts could help explain why so few Trophomera specimens have been obtained from their host so far The present study demonstrates that parasites can occur throughout the entire ocean depth and that they likely occur in

In light of deep-sea mining industry development particularly interested in massive-sulphide deposits enriched in metals with high commercial value efforts are increasing to better understand potential environmental impacts to local fauna The aim of this study was to assess the natural background levels of biomarkers in the hydrothermal vent shrimp Rimicaris exoculata and their responses to copper exposure at in situ pressure (30 MPa) as well as the effects of depressurization and pressurization of the high-pressure aquarium IPOCAMP R exoculata were collected from the chimney walls of the hydrothermal vent site TAG (Mid Atlantic Ridge) at 3630 m depth during the BICOSE cruise in 2014 Tissue metal accumulation was quantified in different tissues (gills hepatopancreas and muscle) and a battery of biomarkers was measured metal exposure (metallothioneins) oxidative stress (catalase superoxide dismutase glutathione-S-transferase and glutathione peroxidase) and oxidative damage (lipid peroxidation) Data show a higher concentration of Cu in the hepatopancreas and a slight increase in the gills after incubations (for both exposed groups) Significant induction of metallothioneins was observed in the gills of shrimps exposed to 4 μM of Cu compared to the control group Moreover activities of enzymes were detected for the in situ group showing a background protection against metal toxicity Results suggest that the proposed method including a physiologically critical step of pressurizing and depressurizing the test chamber to enable the seawater exchange during exposure to contaminants is not affecting metal accumulation and biomarkers response and may prove a useful method to assess toxicity of contaminants in deep-sea species

Range shifts are of great importance as a response for species facing climate change In the light of current ocean-surface warming many studies have focused on the capacity of marine ectotherms to shift their ranges latitudinally Bathymetric range shifts offer an important alternative and may be the sole option for species already at high latitudes or those within enclosed seas yet relevant data are scant Hydrostatic pressure (HP) and temperature have wide ranging effects on physiology importantly acting in synergy thermodynamically and therefore represent key environmental constraints to bathymetric migration We present data on transcriptional regulation in a shallow-water marine crustacean (Palaemonetes varians) at atmospheric and high HP following 168-h exposures at three temperatures across the organismsrsquo thermal scope to establish the potential physiological limit to bathymetric migration by neritic fauna We observe changes in gene expression indicative of cellular macromolecular damage disturbances in metabolic pathways and a lack of acclimation after prolonged exposure to high HP Importantly these effects are ameliorated (less deleterious) at higher temperatures and exacerbated at lower temperatures These data alongside previously published behavioural and heat-shock analyses have important implications for our understanding of the potential for climate-driven bathymetric range shifts

Spatial distribution size composition feeding habits and dynamics of abundance of Alaska skate Bathyraja parmifera in the North Pacific

Grigorov IV Orlov AM amp Baitalyuk AA (Sep 2015)

Journal of ichthyology 55 (5) 644-663

New data on sexual dimorphism and features of reproductive biology of Alaska skate Bathyraja parmifera from the western Bering Sea and the northern Sea of Okhotsk are presented Based on comparative analysis of 11 external morphological characters the males differ from the females in the length of the disc and snout length (to the eyes to the mouth and to the nostrils) In the western Bering Sea 50 of the females and 50 of the males reach the first sexual maturity at 845 cm TL and 852ndash902 cm TL respectively in the Sea of Okhotsk 50 of the males reach their first sexual maturity at 808ndash838 cm TL (the assessment depends on the features of the method) Among smaller skates (less than 45 cm TL) the males prevail but the proportion of the females increases in larger size groups the sex ratio becomes equal in the exemplars 60ndash80 cm TL but the males prevail again among the largest fishes (more than 80 cm TL)

Journal of Soft Robotics 3(1) 23-33

This article presents the development of an underwater gripper that utilizes soft robotics technology to delicately manipulate and sample fragile species on the deep reef Existing solutions for deep sea robotic manipulation have historically been driven by the oil industry resulting in destructive interactions with undersea life Soft material robotics relies on compliant materials that are inherently impedance matched to natural environments and to soft or fragile organisms We demonstrate design principles for soft robot end effectors bench-top characterization of their grasping performance and conclude by describing in situ testing at mesophotic depths The result is the first use of soft robotics in the deep sea for the nondestructive sampling of benthic fauna

Global diversity and biogeography of deep-sea pelagic prokaryotes

Salazar B Cornejo-Castillo FM Beniacutetez-Barrios V et al (2016)

The ISME Journal 10 596ndash608 doi101038ismej2015137

The deep-sea is the largest biome of the biosphere and contains more than half of the whole oceanrsquos microbes Uncovering their general patterns of diversity and community structure at a global scale remains a great challenge as only fragmentary information of deep-sea microbial diversity exists based on regional-scale studies Here we report the first globally comprehensive survey of the prokaryotic communities inhabiting the bathypelagic ocean using high-throughput sequencing of the 16S rRNA gene This work identifies the dominant prokaryotes in the pelagic deep ocean and reveals that 50 of the operational taxonomic units (OTUs) belong to previously unknown prokaryotic taxa most of which are rare and appear in just a few samples We show that whereas the local richness of communities is comparable to that observed in previous regional studies the global pool of prokaryotic taxa detected is modest (~3600 OTUs) as a high proportion of OTUs are shared among samples The water masses appear to act as clear drivers of the geographical distribution of both particle-attached and free-living prokaryotes In addition we show that the deep-oceanic basins in which the bathypelagic realm is divided contain different particle-attached (but not free-living) microbial communities The combination of the aging of the water masses and a lack of complete dispersal are identified as the main drivers for this biogeographical pattern All together we identify the potential of the deep ocean as a reservoir of still unknown biological diversity with a higher degree of spatial complexity than hitherto considered

such environments Using methods described in Phillips et al 2016 (also listed in this issue of Deep-Sea Life) mobile luminescent sources were imaged at a lsquoblack smokerrsquo chimney located at approximately 1640m on the Galapagos Spreading Center While accurate identification of the bioluminescent animal was unfortunately impossible based on video recorded directly prior to the low-light recordings it is hypothesized to be a free-swimming shrimp These observations are placed in context with previous work on light at deep-sea hydrothermal vents and stimulate further interest in researching the role of bioluminescence among chemosynthetic ecosystems

Observations of in situ deep-sea marine bioluminescence with a high-speed high resolution sCMOS camera


Deep-Sea Research I 111 102-109 doi101016jdsr201602012

Observing and measuring marine bioluminescence in situ presents unique challenges characterized by the difficult task of approaching and imaging weakly illuminated bodies in a three-dimensional environment To address this problem a scientific complementary-metal-oxide-semiconductor (sCMOS) microscopy camera was outfitted for deep-sea imaging of marine bioluminescence This system was deployed on multiple platforms (manned submersible remotely operated vehicle and towed body) in three oceanic regions (Western Tropical Pacific Eastern Equatorial Pacific and Northwestern Atlantic) to depths up to 2500 m Using light stimulation bioluminescent responses were recorded at high frame rates and in high resolution offering unprecedented low-light imagery of deep-sea bioluminescence in situ The kinematics of light production in several zooplankton groups was observed and luminescent responses at different depths were quantified as intensity vs time These initial results signify a clear advancement in the bioluminescent imaging methods available for observation and experimentation in the deep-sea

A new book on Biological Sampling in the Deep Sea has been published by Wiley-Blackwell This was an initiative dating from 2009 under the Census of Marine Life programme originally devised by the CenSeam (Census of Marine Life on Seamounts) project but ultimately involving people from all the deep-sea Census projects The book represents the first comprehensive compilation of deep-sea sampling methodologies for a range of habitats The 19 chapters review the real life applications of current and in some instances developing sampling tools and techniques These cover a wide range of sampling gear giving information on the variety of equipment used their pros and cons and operational details Chapters are included on survey and sampling design as well as the handling and processing of samples information management and data analysis advice The book has involved 60 authors and draws upon the experiences of those at the ldquocoal facerdquo of deep-sea sampling expanding on the existing methodological texts whilst encompassing a level of detail often omitted from journal publications It is hoped that the book will promote international consistency in sampling approaches and data collection advance the integration of information into global databases and facilitate improved data analyses and consequently uptake of science results for the management and conservation of the deep-sea The book release started in the UK in March and was launched in New Zealand on NIWAs deep-sea research vessel Tangaroa by the three editors (Malcolm Clark Mireille Consalvey Ashley Rowden) in April (see photo) More details from

Environmental Drivers of Benthic Flux Variation and Ecosystem Functioning in Salish Sea and Northeast Pacific Sediments

Belley R Snelgrove PVR Archambault P Juniper SK (2016)

PLoS ONE 11(3) e0151110

The upwelling of deep waters from the oxygen minimum zone in the Northeast Pacific from the continental slope to the shelf and into the Salish Sea during spring and summer offers a unique opportunity to study ecosystem functioning in the form of benthic fluxes along natural gradients Using the ROV ROPOS we collected sediment cores from 10 sites in May and July 2011 and September 2013 to perform shipboard incubations and flux measurements Specifically we

44


measured benthic fluxes of oxygen and nutrients to evaluate potential environmental drivers of benthic flux variation and ecosystem functioning along natural gradients of temperature and bottom water dissolved oxygen concentrations The range of temperature and dissolved oxygen encountered across our study sites allowed us to apply a suite of multivariate analyses rarely used in flux studies to identify bottom water temperature as the primary environmental driver of benthic flux variation and organic matter remineralization Redundancy analysis revealed that bottom water characteristics (temperature and dissolved oxygen) quality of organic matter (chl aphaeo and CN ratios) and sediment characteristics (mean grain size and porosity) explained 515 of benthic flux variation Multivariate analyses identified significant spatial and temporal variation in benthic fluxes demonstrating key differences between the Northeast Pacific and Salish Sea Moreover Northeast Pacific slope fluxes were generally lower than shelf fluxes Spatial and temporal variation in benthic fluxes in the Salish Sea were driven primarily by differences in temperature and quality of organic matter on the seafloor following phytoplankton blooms These results demonstrate the utility of multivariate approaches in differentiating among potential drivers of seafloor ecosystem functioning and indicate that current and future predictive models of organic matter remineralization and ecosystem functioning of soft-muddy shelf and slope seafloor habitats should consider bottom water temperature variation Bottom temperature has important implications for estimates of seasonal and spatial benthic flux variation benthicndashpelagic coupling and impacts of predicted ocean warming at high latitudes

Cruise NewsIIOE-2 ndash First Expedition December 2015

IIOE India ESSO-Indian National Centre for Ocean Information Services Hyderabad INDIA

The first expedition on board Research Vessel Sagar Nidhi conducted as a part of the IIOE-2 concluded at Mauritius after exploring the western Arabian Sea for 18 days The voyage was flagged of by the Hon Minister of State for Science and Technology and Ministry of Earth Sciences Mr Y S Choudhary at a function held at Mormugao Goa on 4 December 2015

The expedition was led by Prof P N Vinayachandran of the Indian Institute of Science (IISc) Bangalore and Dr Satya Prakash of the ESSO-Indian National Centre for Ocean Information Services (ESSO-INCOIS) Hyderabad Twelve Indian Scientists participated representing IISc INCOIS NIOT (Chennai) NCAOR (Goa) NRSC (Hyderabad) and Goa University In addition to scientists from India there were participants from Mauritius Israel Singapore Australia and the UK

The main goal of this multi-disciplinary scientific expedition was to understand the structure of water masses in the western Indian Ocean along 67degE and assess

the difference in their characteristics with respect to observations made in the past The other objective of the cruise was to understand the physical-chemical-biological characteristics in the equatorial Indian Ocean and their inter-relationships Underwater profiles of currents temperature salinity oxygen light and chlorophyll were measured during the cruise In addition samples have been collected to a depth of 1000 m for various chemical and biological analyses Samples of zooplankton were collected using nets towed from the stern of the ship

It is expected that the data collected during this expedition will elucidate the currents and water masses in the western Indian Ocean in detail and thus further our understanding of the oceanography of the Indian Ocean
